New submission from Michał Górny <mgo...@gentoo.org>:
The _uuid extension fails to build on my Gentoo/FreeBSD system:

Apparently the cause is that it includes headers belonging to the system uuid
library and libuuid (from util-linux) simultaneously. The whole module seems
to be written with the assumption that the two different implementations will
not be present simultaneously. However, some software supports libuuid only,
so we're forced to have both.
Attaching the complete build log. I will submit a PR soonish.
